Add CVC code field to Authorize.net Credit Card Plugin

My client has purchased Authorize.net Credit Card plugin that I have installed and it works great. However, for safety reasons I'd like to add a field for 3-digit security code on credit cards. Is there a way to do this?

Also, I have noticed that if I insert fake data when checking out, site says my order is processed (even though technically its not possible) - is there a way to make program 'recognize' fake entries and display a message accordingly?
